which the following is a specifigation. I

This invention towers.

It'isthe principal object of the present invention to'provid'e a water-cooling tower of the atmospheric type which is of simple con struction and so designed as be formed relates to Water cooling from composite units formed'at-the plant and adapted to be readily assembled at the point of installation, thereby insuring that theerection process may be rapidly carried on and that the cooling tower when finished will be of a predetermined standard design.

[The present invention contemplates the use of a main frame and a plurality of side and corner units adapted to be assembled relative to the main frame in a manner to produce a cooling tower of any predetermined capacity.

The invention is illustrated in the accompanying drawings. in which: Fig-ure'l is. a view in side elevation showing a tower of the present construction with parts broken away to'more clearly show the structural details.

The present invention is particularly concerned with a cooling tower of the general type shown in my Patent. No. 1,33%,515. is-- sued'llf arch 23. 1920.- fi11(1 entitled Water coolingtower. i In that patent. -however,

the cooling tower is gradually built up-from slat and frame memberswhile'in the present instance the frame isongmally built, thereframe members here indicated asheing formed of wood. Euitable 'ma-l braces;

12 are used to secure the nor posts in rigid relation to each other while the'horizontal frame members 11 ar adapted to cross each other at the post. nd to be ac cured thereto. Attention is r cted the fact that the horizontal mom a project a considerable distance from the w rtical "faces (ill of the posts, thus forming out hearing sup ports for the louvres 13. These louvres are of composite construction and comprise side louvre sections 14, and corner sections 15. Each of the sections consists of grooved end rails 16 into which the. opposite ends of the louvre boards 17 project. It is preferable that the louvre boards shall overlap each other at their joints thereby providing a substantially water tight wall which will prevent leakage of? the" water in the cooling tower and also shield the central portionof the tower from the action or Wind. The louvre walls extend upwardly and outwardly at angles of substantially 45. while the Sections are bolted by their lower edges'to the.

horizontal frame members 11-at points near the posts 10 and by their upper edges to the outer ends of the horizontal frame members, thus being supported in their inclined positions.) In this manner the upper edgesof the louvre walls will conceal thelow'er edw of the super adjacent Walls, thus forming a complete wind break while permitting free circulation of air between the various walls.

In the drawings the cooling tower is formed and between the horizontal frame members while the sections 15 are secured diagonally acrossthe corners of the towerand between the projections of the horizontal frame mem hers crossing at the posts.

- LIQUID-FUEL-FEEDING means.

Application filed August 2%, 1919, Serial No. 320,213. Renewed. September 14, 1922. Serial I30. 588,288.

To all whom it may concern:

Be it known that I, JoHN SCHEMINGER,

.Jr., a citizen of the United States, residingat Providence, in the county of Providence 5 and State of Rhode Island, have invented certain new and .useful Improvements in Liquid-Fuel-Feeding Means; :and l do' hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and i use the same. g This invention relates to devices for feeding liquid fuel burners and particularly rotary oil burners. f

The primary object of the invention is i I to provide means for effecting a steady and uniform feed or flow of the liquid fuel from a pump to the burner or other device with which my: invention may be used unaffected by the pulsations of thepump, which, in pump-fed liquid fuel burners as heretofore constructed seriously interferes with the operation of the burner resulting at times in extinguishing the flame.

In the operation of pump-fed rotary oil burners, it is difficult, if not impossible, to prevent the flame from becoming. exti'n guished when the liquid fuel is conducted direct from the pump to the burner, because of the agitation or pulsatory action'of the pump-piston on the moving column of.

liquid-, and the primary object of my inven: tion is to overcome this difliculty and"pro- I vide means whereby a portion of the mov-.

ing column of liquid fuel in its passage from the 'pump* to the burner is separated from the major portion and the air con tained therein and caused to descend and 40 flow quietly to the burner or other device 'unafi'ected by the agitation or pulsations produced by i the pump piston, while thelarge; portion is caused to pass in a conltinuously ascending. column to a pointfrom which it may descend or be delivered into a receiving tank or vessel and returned therefrom to the source from which it came.

The" invention will first be hereinafter more particularly described, with reference to the accompanying drawings, which are to be taken as -1a part of this specification,

and then pointed out in the claims at the end of the description v Insaid drawings;

Fig. 1 is a vertical sectional elevation of an oil separating and quieting device or ap- I .paratus embodying my invention;

Fig. 2 is a transverse section of the same taken on the line 22-of Fig. 1, and Fig. 3 is a vertical sectional elevation of an apee paratus embodying my invention, showing a rotary pump interposed in the pipe connections between the oil tank or source of supply and theoil separating and quieting device; the pump being of the form shown up my'application, Serial No. 315,983, filed August 7, 1919, for improvements in thermally controlled rotary oil burners.

Referring to said drawings, in which the same reference letters are used to denote corresponding parts in difierent views, the letter A denotes the oil separating device, or separating and settling chamber, which is. interposed in the pipe connections leading from the pump P to the burner or other device (not shown), the pump being con nected with an oil tank or other-source of liquid fuel supply throu h the pipe and discharging into a pipe B which 'co-nducts the liquid into the receiving chamber a of thereof and the other reduced end at the top. A vertical partition C extends'up- -'wardly from the. bottom or reduced end portion'of the. casing toa point near its top, thus forming a receiving chamber at one side of said partition and a settling chamber at the other side thereof, At the bottom of the settling chamber a? there is an" outlet opening with which is connected a pipe. D into which the quieted -li id is discharged. Said pipe D is ,connecteh' the feed pipe for supplying fuel tothe burner or other-device. A portion of the liquid entering the receiving chamber a is forced upwardly by the pump-Pinto and tor, while a smallerportion flows'into the settling chamber a "-As the oil passes over globules of air contained therein and is thereby condensed and caused to pass to the burner in a quiet or non-turbulent and steadily flowing stream. Thev pipe E has a check with through a pipe E at the top of the separa- 10b valve therein, at e, to prevent back flow when the pump is stopped. This pipe ex-. tends upwardly to a' predetermined point so that the major portion of the liquid passing through the separator is caused tov settling chamber efi'ects the passage thereof quietly, continuously and evenly to the burner or other device unaifected by the pulsations or irregular movements of the pump piston or pistons. The diamondshaped form of the separatorcasing is preferred, though not indispensible, as a cylindrical, square or other form may be used,

.and various other changes may be made in the details and arrangement of parts without departing from the spirit and scope of my invention.

The operation of the apparatus will be readily understood from the foregoing description, when taken in connection with the accompanying drawings. As will be seen, the oil under pressure is conducted into the receiving compartment of the separating apparatus and the major part thereof is forced into a continuously ascending column through and out of the pipe E, and thence into a receiving tank or containeror back to the source of supply while a part of the oil is carried over the top-of the partition C and caused to descend and flow quietly to the burner or other device unaffected by the agitationor pulsation of the pump to which the ascending columnof liquid is subjected.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent is: p

' '1. Oil feeding means comprising asupply tank, a circulating system including a pump and means for separating the oil and cansing the larger portion to return to the tank while the lesser portion is caused to pass quietly and evenly to a burner or other deviceunaffected by the pulsations of the pump. I

2. In combination',.a liquid 'fuel supply tank, a pump and means whereby the liquid sage of the latter to the burner or other de-- vice unaffected by the pulsations of the pump.

3. Liquid fuel feeding means for a burner or other device, comprising a tank or source of supply, a pump, a separating and quieting apparatus, and pipes connecting said pump with said tank and said apparatus, whereby the oil drawn from the tank is divided into unequal portions and the larger portion caused to move in an ascending column to a predetermined point and then return to the tank, the ascending column being adapted to exert back pressure acting on the smaller portion and with the aid of the pump causing said smaller portion to pass quietly and evenly to the burner or other device unaffected by the pulsations of the pump.

In testimony whereof I affix my signature in the presence of two witnesses.
